SpaceMan 99 benefits

Byte for byte duplicate file finding
Since version 1, SpaceMan 99 has always supported true byte for byte comparison of files to determine if two files are identical. This method guarantees that when duplicate files are found, the duplicate files are identical. Using checksums may be quicker, but there is always a chance that two non-identical files may have the same checksum. Newer versions of SpaceMan 99 also support the use of checksums to test if two files are identical, but always as a user option so you can decide whether to trade speed of scanning for the small chance that two non-identical files may appear to be identical.
SpaceMan 99 uses intelligent algorithms so that even when byte for byte testing for duplicate files is selected, it first tries other quicker methods to determine if two files are different.
Powerful and easy to use tools to delete duplicate files
Once duplicate files have been identified, the most common next step is to delete all of them except one. SpaceMan 99 pioneered the methods for selecting files to delete from a set of duplicates. These include selecting all files in a folder that have duplicates elsewhere in the file system, or all files outside a particular folder that have duplicates in that folder. SpaceMan 99 uses a two stage process for deleting files. Files are first marked for deletion, at which point the complete list can be reviewed. Once you are happy with the list, the marked files can be deleted. SpaceMan 99 uses the Windows system delete command to delete files, so provided you have selected the Windows option to send deleted items to the recycle bin, you can always undo deletions anyway.
Clear reporting of duplicate files
This is one of the things often commented on by users. SpaceMan 99 shows the duplicate files found in a very clear and intuitive way.



This image shows the SpaceMan 99 main window. As you can see the top half is similar to Windows File Explorer, except that each folder also shows the total amount of disk space used by all files under it. Also, each file shown in the list in the top right panel has a symbol next to it that shows if any other copies of the file have been found.

The bottom half shows duplicate files. The list in the bottom left panel shows each set of identical files found, one set per line. The list in the bottom right panel shows the identical files in the currently selected set.

Brief description of main areas

Folder BrowserLets you browse the folders on your system. Click the check-box next to the top level folder you want to scan. Sub-folders will automatically be scanned.
File BrowserShows the files and sub-folders in the current folder.
Duplicates ListShows all the duplicate files that have been found. Each line is a set of duplicate files.
Duplicate FilesShows each of the files in the currently selected duplicates set.
Current FolderShows the path to the currently selected folder. In addition to using the folder browser, you can type or paste into this box to select a different folder.
ToolbarContains buttons for some of the most common commands.
Find Duplicate OptionsLets you control how duplicates are found. For example, if you want absolute certainty that duplicate files are exactly the same, you can select a byte for byte comparison. However, if you want a faster scan you can get results more quickly by just comparing file checksums and size.
